Factor V Leiden, PT 20210
This test is done to determine whether you have an inherited gene mutation that increases your risk of developing venous blood clots. This test is done when you have had an unexplained clotting episode, especially when you are relatively young (less than 50 years old) and have no other identified risk factors.
PREPARATION FOR TEST
A blood sample is obtained by inserting a needle into a vein in the arm.
No genetic defect is found (negative).
Ranges for normal findings may vary among different laboratories and hospitals. You should always check with your doctor after having lab work or other tests done to discuss the meaning of your test results and whether your values are considered within normal limits.
MEANING OF TEST
Your caregiver will go over the test results with you and discuss the importance and meaning of your results, as well as treatment options and the need for additional tests if necessary.
OBTAINING THE TEST RESULTS
It is your responsibility to obtain your test results. Ask the lab or department performing the test when and how you will get your results.
